| Robert 16-Aug-2010 [4478x2] | But I won't enter any Kindergarten discussions that are not moving us forward or where some go nuts because we have clear red thread we follow and don't care to much what they think. |
That's it. Overall, IMO we have moved R3 forward much faster and with greater progress than before. And it's not only because we are now coding everything etc. By far not. But at least we have helped to get more momentum to R3. | |
| shadwolf 16-Aug-2010 [4480x3] | android is linux based ... i have one on my acer laptop that's a short linux ... |
on acer the android don't have access to android market ... | |
instead of having an android phone maybe the devtools include an emulator no ? | |
| Gregg 16-Aug-2010 [4483] | Thanks Robert. I like the fact that a goal is the use of R3 to build commercial apps. That means things like accelerator keys and other features have a better chance of being seen as important. |
| Carl 17-Aug-2010 [4484] | http://www.rebol.net/r3blogs/0329.html- about callbacks |
| Oldes 17-Aug-2010 [4485] | cool... will be there any examples as well? |
| Robert 17-Aug-2010 [4486x2] | (OT: Our world is back online) |
Carl, great news! I'm ready :-) | |
| Robert 18-Aug-2010 [4488] | I have a XML file and want to handle it by tags like a nested block. Are there are any tricks? Or do I need to use PARSE / FIND etc. |
| Gregg 18-Aug-2010 [4489x2] | So, you want to use path notation on the parse XML? |
parsed XML | |
| Robert 18-Aug-2010 [4491x2] | I would like to extract a set of elements like: Everything between <TAG> ... </TAG> |
TAG should be specified. | |
| Gregg 18-Aug-2010 [4493x2] | What I mean is, do you want to convert the XML to a block and then access it like this? data/tag |
Or do you just want to parse the raw data out of the XML between those two <tags>? | |
| Robert 18-Aug-2010 [4495x2] | No, not necessary. |
Yes, just raw data. | |
| Gregg 18-Aug-2010 [4497x3] | Just use PARSE then. I have a solution for the block approach, but just use PARSE when I need to extract data in more stream-oriented ways. |
Give me a minute though, I might have something... | |
This was used with small pieces of XML, rather than entire documents, but might be a starting point for you. xml-get-field: func [input name /local xml-field= data other-name] [ xml-field=: compose/deep [ some [ (rejoin ["<" name ">"]) copy data to (rejoin ["</" name ">"]) to end | skip ;(to paren! [prin '.]) ] ] either parse input xml-field= [data] [none] ] | |
| Robert 18-Aug-2010 [4500] | Ok, thanks. |
| Sunanda 18-Aug-2010 [4501] | I've used Gavin's XML-object.r in a couple of projects. Not tried it under R3 though: http://www.rebol.org/view-script.r?script=xml-object.r |
| Gabriele 19-Aug-2010 [4502x2] | http://www.rebol.it/power-mezz/parsers/ml-parser.html |
inside?: no
parse-ml "...your text..." func [command data] [
either inside? [
?? command ?? data
if command = </tag> [inside?: no]
] [
if command = <tag> [inside?: yes]
]

| Chris 19-Aug-2010 [4504] | ; Another flavour of Rebol XML: do http://www.ross-gill.com/r/r3xml.r doc: load-xml/dom location foreach tag doc/get-by-tag <a> [ probe tag/flatten probe tag/text probe tag/get #href ] |
| Robert 19-Aug-2010 [4505x2] | Chris, you post can now be done native using DECODE. Carl added this yesterday. |
I proposed a change to how path notation works on TAG! to return name value blocks for attributes. | |
| Chris 19-Aug-2010 [4507x2] | Decode loads an XML document? |
Is there docs on the change? | |
| Graham 19-Aug-2010 [4509] | even better would be to release the binaries! |
| Graham 20-Aug-2010 [4510x2] | http://www.rebol.com/cgi-bin/blog.r?view=0484#comments Does any one have write access, or is Carl mistaken ? |
ie. anyone with a rank of 50 or higher | |
| Robert 20-Aug-2010 [4512x4] | Here is how it works: |
Added it as a codec so you can access it: >> ml: decode 'markup read http://www.rebol.com >> foreach tag ml [probe tag] <!doctype html> ^/ <html> <head> ^/ <meta name="generator" content="REBOL WIP Wiki"/> ^/ <meta name="date" content="10-Aug-2010/12:18:33-7:00"/> ^/ <meta name="rebol-version" content="2.100.97.4.2"/> ^/ <meta http-equiv="Content-Type" content="text/html;charset=UTF-8"/> | |
It's a simple way to traverse over tags. | |
No fancy thing yet. | |
| Pekr 20-Aug-2010 [4516] | btw - codecs were supposed to be redone, using port mechanism, to allow streaming etc. Is this the case already, or not? |
| Robert 20-Aug-2010 [4517] | Don't know. DECODE doesn't look like a port to me. Maybe on the lower level this is done via a port like mechanism. |
| Chris 20-Aug-2010 [4518] | Equivalent to load/markup then? With respect, that's not exactly the same as the example I posted... |
| Robert 20-Aug-2010 [4519] | Yes, that's the missing part I made a proposal for to Carl. |
| Chris 20-Aug-2010 [4520] | r3xml is an R3 port of AltXML, a Rebolised version of XML DOM: http://bit.ly/XMLandREBOL |
| RobertS 20-Aug-2010 [4521] | 2.100.99.3.1 the use of function at with negative index simply returns the whole series - which reminds me to ask why at with index 0 doe not return the series atfter the last item i.e. place you at the end of the series? The docs for at specify behavior for a negative index "Using a negative index N, you can go N values backwards in a series:" PS I have relocated to Fredericton, NB, Canada. Lovely, green and interesting. |
| Graham 20-Aug-2010 [4522x2] | Chris, with the hostkit you can compile in your own functions such as r3xml |
Carl ... http://www.rebol.com/cgi-bin/blog.r?view=0484#comments ... big typo at the top of the page! | |
| Chris 20-Aug-2010 [4524] | G: I'm not clear on how to get to that point or how to do that. Or if it's worthwhile? |
| Graham 20-Aug-2010 [4525x3] | well, there's only the one protocol included so far .. if you want your own, you have the option of including, or loading afterwards |
Thanks Ladislav for confirming the lack of write access to the rebol.com wiki | |
Chris, how to include your own protocols http://jira.rebolsource.net:8080/browse/REBOLKIT-2 | |
